I've had a lot of fun with the Webster series of young children's books which started out by teaching web etiquette and safety, and have now migrated in this volume to things electronic. In a series of rhymes, Webster gets to learn what to do with anything noisy that flashes or beeps.
Illustrated with amusing pictures of the Webster spider family (which curiously has canines and only two eyes while retaining eight limbs!) and told in neat little rhymes, this story will hopefully educate your kids as to when electronics need to be subsonic. There's a lot to learn though, so you may have to read this to your child many times before they (hopefully!) absorb it all. You could turn this into a memory contest. I recommend this one.
